The Big Gun X Double Adjustable Twin Tube shocks are specifically valved for high horsepower
drag radial tire equipped applications. Drag radial competitors require a unique valving package
to control the rear suspension and properly apply the radial tire to the track. Superior traction is
achieved through a high flow piston that delivers consistent performance, pass after pass. If you
have 1,000 - 1,500 horsepower and are on a drag radial tire, this is the valving package
you need to complement your race program. For quicker adjustments, mount your AFCO
shocks upside down for unsprung weight savings and ease in accessing the rebound adjuster.
